Namespaces

This example shows how to use namespaces to organize code and avoid naming conflicts.

cppCopy code#include <iostream>

namespace Math {
int add(int a, int b) {
    return a + b;
}
}

namespace StringUtils {
void printHello() {
    std::cout &lt;&lt; "Hello, World!" &lt;&lt; std::endl;
}
}

int main() {
std::cout &lt;&lt; "Sum: " &lt;&lt; Math::add(3, 4) &lt;&lt; std::endl; // Output: Sum: 7
StringUtils::printHello(); // Output: Hello, World!
return 0;
}
